Summary

Story summary

Chiba University researchers developed a supramolecular polymer system that changes its structure in response to light intensity, enabling transitions among 1D, 2D, and 3D forms.
Under strong UV light, the material reverts to 1D nanofibers.
Under weak UV light, larger nanosheets grow vertically through Ostwald ripening.
The work, published in Chem, points to potential smart-material applications such as self-healing surfaces and adaptable drug-delivery systems.
